Ok, I did the Complete installation.
On a side note, I think Substance should go further with Batch Import ... I mean, we have to use Batch Import, which creates Substance nodes with the proper materials, and then we have to select each material, for finally click on the Substance To Corona function in Substance menu. It's not even able to work on multiple Substance maps in one go :( Or am I missing something ? this should be much more straight forward IMO: Batch Import to Corona, and Substance nodes are created along with Corona materials, and voilĂ :P
